Around Bedminster, finding it before your engine runs normally leaves a drain and a thorough flush on the spot. Here in advance? In that case what follows explains how it comes about and how to stop it ever happening. ## AdBlue in a diesel car, and its separate tank Many newer diesels around Bristol, as well as Bedminster, run on two fluids; your motor gets only your diesel. AdBlue's own tank holds it, and from there it goes to the exhaust, where a spray treats the fumes. Each tank has its own filler. Plenty of cars have a single flap for the two, while others put the AdBlue filler to the boot or under the bonnet. The diesel side is filled at the petrol pump all the time. Seldom filled, AdBlue normally comes out of a bottle, tipped by someone who must stop and think what cap to use. The error lives in that gap. ## How AdBlue in the diesel tank happens in Bedminster Three things tend to come together, and carelessness is seldom one of them. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the car drops into limp mode. So the top-up is done in a hurry: on a drive off Dartmoor Street before work, or in the car park outside The Masonic on the way home. Then the vehicle is new. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand reaches for the cap it would have used on the old one. Nothing halts the tip after it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it occurs in Southville or the middle of Bedminster, it's the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Before you pour anything, whether on a drive in Clifton Wood or a forecourt in Bedminster, check these. They take a few seconds. - The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap normally is not. Read it instead of going by position. - Plenty of vehicles give AdBlue the smaller neck of the two. - Check inside your fuel flap: many vehicles carry a label there showing which fuel goes where. - In the boot or under the bonnet: that is where your filler sits if it is not by the diesel cap, and the handbook tells you which. - Collecting a hire or company car, say at the car park outside Parson Street? Check with the person who drove the vehicle last before you set off, rather than once the light goes on. ## AdBlue top-ups that never reach your diesel tank On the day the warning appears — wherever it is in Bristol — a routine to follow. - Stop on level, motor off, with time to spare — not rushing on the side of North Street. - Find the AdBlue filler, read the cap, and speak the word "AdBlue" out loud as unscrewing it. It sounds daft. It does the trick. - Both behind a single flap? So confirm the cap on the diesel side stays closed before raising the bottle. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only then, start the car: close the cap, check once more, and make sure the diesel cap was never opened. Find at stage two or three that it has already gone into the diesel side? So stop just there. Do not go on to stage five. ## Put AdBlue in the diesel tank in Bedminster already? Then the order of things is short. Don't start your engine. Don't switch the ignition on; on many diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is drawn from — so do not top up with diesel to thin it. If you are at a forecourt, whether it is the Harvest Energy or the Texaco, ask the staff to help push the vehicle away from the pump. If you're on your own driveway around Bedminster, leave the car where it is. Stop as soon as it is safe then switch off, if the motor has already run. The next junction is where to leave if you're on the M32, under 3 miles from Bedminster. Tell us about how far it went: a run towards Bristol, under a mile away, is a bigger job than a short hop across Bedminster. ## When our technicians get there around Bedminster, what takes place? Our engineers come to the vehicle wherever it has stopped, whether that is outside Compass Point Primary School, close to Cat & Mouse or on your own driveway. Those replies settle this work and the quote, and so our technicians ask what got in, roughly how much, and whether it has run. During the phone call itself, you hear our price — ahead of anything else. Emptying the tank comes next, followed by a thorough flush of your system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. The motor is fired up next and checked to be sure it runs smoothly, all before we leave. If the engine has not run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night. Your insurer usually wants the engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. While we travel, take a look at your insurance documents; plenty include cover for misfuelling. ## About Bedminster Bedminster is a suburban area in Bristol, situated on the south bank of the River Avon, with a mix of terraced housing and local amenities.
